My 1.4GHz Tualatin-S RDD has begun to have problems with the 3.5" floppy drive, spitting out invalid Track 0 error at every disk I put in the drive. After a very long and time consuming troubleshooting, I've replaced the cable with a new one, which was indeed the culprit, or better to say, one of the culprits: many of my disks were bad or have become bad in the blinking of an eye, even after formatting them. So I've separated the working ones from the bad ones and now at least I have a set of 3.5" disks that I know for sure that work, for now.
On the other hand, if it counts as a retro activity, I decided to bite the bullet and buy a new motherboard for my system, and my choice went for the Asus TUV4X. Apparently this motherboard is very overclocking friendly and should let me overclock my Tualatin more safely than on the Advance 10T I currently have. The only drawback is that I lose the ISA slot, so no AWE64 Value for me, but at least has four SDRAM slots and so, theoretically, I could expand the memory up to 2GB. That's interesting, because I heard that the previous generation of the motherboard, the CUV4X, also supports 1GB SDRAM modules... I wonder if the TUV4X has the same undocumented feature... If so, I might be able to expand the RAM up to 3.5GB, since I have three 1GB ECC PC133 sticks.
